Ok so just bought this camera for the high speed usb 3.0 interface, works on usb 3.0 until i connect a repeater extension cable, then it shows as usb 2.0, so bought another repeater extension cable (a good quality 1) same problem, reading on some forums it says this camera is pretty useless at working on usb 3.0, so why sell it with usb 3.0 as a sales pitch, isnt that false advertising????????
